The present paper deals with an analysis of the kinematics and geometry of the tooth engagement of a wave gear drive comprising a rigid gear and a flexible gear in a wave-like motion such as a circular spline and a flexspline in Harmonic Drive. The analysis is carried out in a plane mechanism. From the analysis of the motion of the rigid gear and the flexible gear, the shapes of the rolling contact plates which move together with each tooth are derived, assuming that the tooth of the flexible gear is rigid, although the tooth groove is flexible, and that the pitch the teeth on the unstrechable neutral line of the flexible gear is constant. Then the tooth profiles of both gears are determined, according to the theory of gear mechanism that the common tooth normal at the meshing point passes through the momentary contact point of the rolling contact plates. As an example, a theoretical new tooth profile of the flexible gear in meshing with involute profile internal rigid gear is obtained.
